The True Food Shoppers Guide, created by the Center for Food Safety, allows consumers to make informed decisions at the grocery store about GMO ingredients.
The guide and phone app offer tips on how to identify and avoid GMO ingredients. They even take it a step further by offering contact information for companies that use GMO ingredients. "This feature enables consumers to personally voice their opposition to the use of GM foods directly to the parties involved."
Companies of the RED list use GMO ingredients and those on the GREEN list have made an effort to avoid GMOs.
